What would be the mesh vertice limitations for a modular character, for mobile platforms?

Hej,

I have read this guide for mesh limitations on mobile platforms that mentions specifically: “All mesh types can have up to 65k vertices due to the lack of 32 bit index support on mobile hardware.”

I have also recently read this article about working with a modular character, and merging together different meshes if you want to allow the user to swap parts on a character, which would be more efficient.

So my question is, what would be the vertices limit on the final merged mesh character? Or does the limit count only for the different parts of the character?
